  • Method for erecting buildings, and structural assembly for carrying out the method
    Patent number: 5291716
    Abstract: A method for erecting buildings is characterized in that cassettes (10) made in a form between sectional elements (11) are positioned, at the building site, in such manner that the sectional elements (11) are close to one another and together define vertical cavities in which preferably concrete is injected to form supporting columns. Horizontal beams (23) are joined to the sectional elements (11) to be connected to the supporting columns when these are being cast, thereby to achieve a structural skeleton. A structural assembly for carrying out this method comprises cassettes (10) made in a form between sectional elements (11). The sectional elements (11) serve as supporting means when the cassette (10) is handled, and as a form for producing supporting columns after the cassettes (10) have been positioned at the building site.
